I was thinking about this BF 50+ forum today while biking on my exercise Rail to Trail.
I did what I do most of the time: Go fast like 17 MPH average with a Hybrid and aerobars.
After 30 miles of that I contemplated: Perhaps I should slow down and look at the flowers and listen to the birds. That is the consensus in the 50+ group.
This trail goes through a swamp area.
After a few minutes of 13 - 15 MPH I said to my-selves: What is going on? All hell broke loose. The bugs descended upon me in unreasonable amounts. Biting me anywhere and getting in my eyes. It took me about 10 minutes of that to figure cause and effect.
I stepped up the speed to above 16 MPH. Problem was solved.
